Every time I get my car up to a speed between 60 mph and 70 mph it like "jumps" and seems like all messed up. The cruise control button on the steering wheel is broken off and it seems like maybe it is stuck pushed down.

I have a 2005 ford explorer. I started loosing oil pressure, so we took off the oil pan to see what was going on. There was plastic chunks in it. I have been told they are the timing chain guides. What I need to know is, what all will I have to replace inorder to fix my explorer?? I just want to get it fixed enough to make it to a dealership and trade it off. Please someone help me out here

its happened several times & after it sits for a bit, it starts. Already has a new starter & alternater. diagnostic readings say that my battery is good. mechanic cant figure out unless it is failing at the time. Should i replace the battery, just in case?

Putting the key in second position most lights come on, then in third position it gets a fast clicking noise and all the dials on the instrument panel go further down then they normally are and are fluttering very slightly in place at the same speed. ABS, check gage, check door ajar, seatbelt light, battery, service engine soon light stay on. Tried two keys, both do the same thing and also getting a low voltage reading. I haven't got a code, would this be a good time to go buy an OBD II? I have the manual, I'm reading everything front to back now to see if I can find out anything. Thanks so much in advance.
